€5,600 SEAI grant available

Window & Door Installation Across Ireland

Single glazing, tired seals and old frames account for roughly a fifth of the heat leaving a typical home — and most of the draughts you actually feel.

SEAI grants up to €4,000 for windows and €1,600 for doors. Standalone since 2 March 2026 — a full retrofit is no longer required, though your home must meet SEAI fabric requirements.

Double and triple glazing

Modern A-rated units use low-emissivity glass, warm-edge spacers and argon fill to hold heat inside. Triple glazing adds a further step for exposed or north-facing elevations and for homes on busy roads, where the drop in noise is often as noticeable as the drop in heating cost.

Doors

Composite and insulated uPVC doors seal properly against wind-driven rain, come with multi-point locking, and stop the cold draught that runs across the hall floor in older houses. Frame colours are matched across windows and doors so the elevation reads as one job rather than two.

What the installation includes

Delivery, removal and disposal of the old units, and full installation are included in every quote. Finishing prepared for painting is available as an add-on so the job is left ready to decorate. We measure every opening ourselves, so units fit correctly first time.

Common questions

Is there an SEAI grant for windows and doors?

Yes. Since 2 March 2026 windows and doors are a standalone SEAI grant — up to €4,000 for windows and €1,600 for doors — so a full deep retrofit is no longer required. Your home must meet SEAI fabric and insulation requirements to qualify, which we confirm at the survey.

Should I choose double or triple glazing?

Double glazing suits most homes. Triple is worth considering on exposed elevations, north-facing rooms and properties on busy roads where noise is a factor.

Do you remove the old windows?

Yes. Delivery, removal and disposal of old units and full installation are included in the quoted price.
